[OpenAFS-devel] Kernel oops

[Herbert Huber]

Hello,

today I got the following kernel oops:

Our dual PIII box is running linux 2.4.0 with high_memory_support and an
openafs-1.0.1 with the patches from Chas Williams (please see mails
"openafs-1.0.1 not working correctly under 2.4.0" from 18 Jan 2001).

Does openafs-1.0.4 support SMP 2.4.x kernels with "High Memory Support"
enabled?
Is the opps listed above any known problem?

Regards
